This invention relates to chimney sweep- I ing apparatus.

An important object of the invention is the provision of 'apparatus forsweeping chim- 5 neys which will eliminate the necessity of climbingupon the roof of a building to install the same. 1 p

A further, and more specific object of the invention is to provide achimney sweeping 10 apparatus having incombination therewith anextensible support which may be manipulated from the ground toplacethersweeping apparatus in proper relation to the chimney foroperation therein.

A further obj ect of the invention is to produce aidevice which may bemanipulated from the ground to cause reciprocation of the sweepingdevice in the chimney.

V A. still further object of the invention is to provide means, forclearing the soot removed from the chimney which is likewise operablefrom the ground.

These and other objects I attain by the construction shown in theaccompanying drawings, wherein for the purpose'of illus. tration isshown a preferred embodiment of my invention and wherein V Figure 1 is aside elevation showing chimney sweeping apparatus constructed inaccordance with my invention in use, parts being broken away;

Figure 2 is a front elevation thereof;

Figure 8 is an enlarged detail view through the brush mechanism;

Figure 4 is an enlarged detail sectional view through the soot pan;

Figure 5 is a sectionon the'line 5-5 of Figure 2.

Referring now more particularly to the drawings, the numerals l0 and 11generally designate the sections of an extensible support similar to anextension ladder. The section 10 has guides 12 in which the section 11is slidable and has at its upper end a pulley 13 over which is trained arope 14, one end of which is secured to the lower end of the section 11and the opposite-end of which is extended to the ground, so that fromthe foot of this support, it may be'extended as to 5 its effectivelength.

. weight are apertured At its upper'end, the section 11' has se curedthereto a groupof legs 15twhich are parellel to one another andacutely:arranged with relation to'the section. tThese-legsldefineasubstantially rectangular opening and *are provided at their lower endswithoutturnedfeet .16 adapted-"to rest upon the cap .of a chimney: G9Above the'c'enter' of the opening defined by the l'eg's -15, the sidemembers of the section ll 'are connected'by trans- :69

verse shaftsorisupports 17mounting sheaves 18 and 19 over which aretrained ropes or cables 20 and 21. I t

The rope 20 is secured to a brush block 22,

the sides of which have connected thereto by 5 springs 23, brushes 24:for engaging the walls ofvthe chimney. I

This block may be formed of any suitable light material and is recessedin its under surface for the reception of a counterweight, 7 designatedat 25. The block and counterfor the passage of the flexible element 21,as indicated at 26. This flexible element beneath the block is attachedto a soot pan 27'which has upwardly flaring I side walls 28, the edgesof which are provided with marginal extensions 29 of rubber or othersuitable flexible material.

In use of the apparatus, the support is extended until the legs 15 maybe positioned to engage the feet thereof with the cap of the chimney.The brushand soot pan are then lowered into the chimney, the soot panbeing loweredto the lower end of the chimney and the brush beingreciprocated therein un- 3 5 til the cleaningoperation is completed.The.

brush is then elevatedwith the pan and may be extendedinto the spacebetween the legs 15 to insure ready disengagement of the de vice fromthe chimney. V The brush and pan may be stored within this space duringtransportation of the device from place to place.

It will be obvious'that a device of this character will eliminate thenecessity for many dangerous climbs in chimney sweeping and will provideanapparatus whereby the sweeping operation may be carried onexpeditiously and efficiently. It will also be obvious that theconstruction hereinbefore set forth is capableof a certain range of 100change and modification without materially departing from the spirit ofthe invention and I accordingly do not limit myself to such specificstructure except as hereinafter claimed. 7 V

I claim':

In a chimney sweeping apparatus, a ladder adapted to be arranged withits upper end extending across the upper end of the chimney, legsextending downwardly from the upper end of the ladder and adapted torest upon the upper end of the chimney to support the upper end of theladder from the chimney, a sweep element provided with a passageextending vertically therethrough, means suspending the sweep elementfrom the upper end of the ladder for vertical movement in the chimney, asoot collector, and means connected to the soot collector and passingthrough the passage in the sweep element and connected to the upperendof the ladder to suspend the soot collector for vertical movementinthe chimney;

In testimony whereofl hereunto affix my signature. or 7 V V DAVID-ALLENSHINN.
